TABLET-HOLDER FOR TYPOGRAPHIC MACHINES.

SPECIFICATION forming part of Letters Patent No. 553,986, dated February 4, 1896.

Application filed April 11, 1894. Renewed August 19, 1895. Serial No. 559,805. (No model.)

To all whom, t may concern:

Be it known that we, THOMAS T. HEATH, of Loveland, Clermont county, and ALOIS N. VERDIN, of Glendale, Hamilton county, Ohio, have invented certain new and useful Improvements in Tablet Holders for Typographic Machines, of which the following is a specification.

In type-writing machines and in matrixmaking machines the impression is made upon or in thin material, such as paper, wood or metal, and generally the tablet or sheet of material to be dealt with has been held either by several of its edges or by some support extending entirely across the sheet back of the line on which the impression is to be made. In the use of such tablet-holders it is found difficult to insert the tablet conveniently, difiicult to avoid buckling the tablet, and difficult to remove and replace the tablet.

Our invention pertains to improvements in tablet-holders for typographie machines, and our improvements will be readily understood from the following description, taken in connection with the accompanying drawings, in which- Figure 1 is a perspective view of a tabletholder exemplifying our invention; Fig. 2, a plan of the same 5 Fig. 3, a perspective rear view of the same.

In Figs. l and 2 the tablet-holder is shown in position in the carriage of a typographie machine, while Fig. 3 shows the tablet-holder and tablet removed from the machine.

In the drawings, l illustrates an exemplifying guide-rail of a typographicl machine on which is to slide the carriage which supports the tablet; 2, the tablet-carriage arranged to slide on the rail and to be moved along the same, letter by letter, by any usual or simple means; 3, the tablet-carrier mounted on the carriage and arranged to slide vertically thereon and to be moved thereon, line by line, as the work progresses, by any usual or suitable mechanism; 4, a rack and pinion illustrating ordinary mechanism for moving the tablet-carrier up and down on the carriage; 5, a iiXed anvil over which the rear surface of the tablet moves, this anvil serving to furnish a backing as the impression is made, it being understood that the impressing device will impress the type at a point against the tablet immediately in front of this anvil; G, a vertical groove in the tablet-carrier 3, this groove being open at one side and channeled upon one of its inner walls; 7, a light but stiff strip of metal easily iittin g the groove 6 and projecting out edgewise therefrom, this strip being of a length suited to the greatest length of tablet material to be dealt with; S, an edgewise projection of the strip 7, the rear surface of this projecting portion 8 being the surface against which the tablet is to seat; 9, jaws projecting parallel with the rear face of the projecting portion S; l0, conically-pointed set-screws in the jaws 9, presenting their points toward the rear face of strip S; 1l, the sheet of tablet materialsay a sheet of paper-with one of `its edges resting against the rear face of strip 8 and held thereto by the points of the set-screws 10, the rear face of the tablet being in the plane of the end of anvil 5, and l2 a stop tor prevent strip 7 from dropping through the carrier 3.

It will be observed that the tablet ll is held by the tablet-holder 7 8 at one edge only, its other edges being free. In this condition the usual feed motions/of the machine will move the tablet past the anvil horizontally letter by letter as each character is impressed, and vertically in line-by-line progression, The tablet is unrestrained excepting at the edge engaged bythe holder. By taking hold of the upper end of the holder it may be pulled up out of the carrier 3, bringing the tablet with it, thus permitting the operator to have in his hand the tablet margined at one edge by the extremely-light strip-like holder. The holder with the tablet is readily replaced by sliding it down again into the carrier.

The holder is readily removed from the carrier when tablets are to be removed or replaced.

The tablet may be removed from the holder and may again be replaced in it with the assurance that it will come in proper relationship to the holdeigthe conically-pointed screws securing accuracy of setting.

Looking at Fig. l it will be observed that the upper end of strip '7 may be taken hold of 'and pulled vertically up out of carrier 3,

thus giving the operator in his hand the sheet ll margined by the strip 7 giving about such a structure, so far as handling is concerned, as an ordinary newspaper-tile, Fig. 3 showing the structure, but reversed. It Will be observed that strip 7 then forms a metal niargin for the edge of sheet ll and that the sheet may be inspected or dealt with, as desired, and again returned with its strip to the carrier. There may be several strips, thus permitting an incomplete sheet to be taken from the carrier and another one in its individual margin-strip inserted. The sheet is at all times entirely free except at the edge margin by the strip 7. There is no plate or other backing for sheet ll, except at the anvil 5, where the sheet is against it.

XVe claim as our invention l. In a tablet-holder for typographie inachines, the combination, substantially as set forth, of a narrow metallic strip having one l of its edge portions adapted to t the tabletcarrier of the machine and having its other and parallel edge portion provided with tablet-clamps. A

2. ln a typographie machine, the combination, substantially as set forth, of a tabletcarrier having a longitudinal seat to receive a tablet-holder, a narrow tablet-holding strip adapted to have one of its edges engage said seat in the carrier, jaws formed at the other edge of said strip, and conieally-pointed setscreWs in said jaws.

3. In a typographie machine, the combination, substantially as set forth, of a sheet of tablet material, a narrow margin-strip having one of its edges clamped to one edge of said` sheet, and a carrier separably engaging the other edge of said strip.
